Description

Hayes Iva, also known as San Diego marsh elder, is an evergreen shrub with a naturally sprawling habit with branches extending to 2 - 3 ft. tall and plants reaching 4 - 5 ft. wide. It is characterized by pale green leaves and spikes covered with tiny yellow flowers during spring.

Hayes Iva is a tough plant that is highly suited to sunny exposures and summer moist or dry conditions. It grows well in both clay and loam type soils throughout the Inland Empire. Throughout this range, Hayes Iva is most often grown on banks and slopes, in parkways and adjacent to natural areas as a low maintenance ground cover. It can be easily trimmed along walkways and topped to achieve a neat appearance.

Water Needs

Hayes iva is well adapted to all parts of the Inland Empire with normal winter rains and low amounts of summer irrigation. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months marked by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; more supplemental water commonly results in a longer growing season and spreading more rapidly.
